Reconfigurable direct space -to -time pulse shaping

Nathaniel A Webster, Purdue University


The Ultrafast optical word generator is an optical fiber communication subsystem under development by several researches in the Ultrafast Optics Lab. This system proposes to take parallel electrical data streams and serialize them onto a single optical channel. Potential applications of the optical word generator include its use in optical time-division multiplexing and also in the encryption of high-speed optical data streams. Two of the main components of the word generator are the direct space to time arrayed waveguide grating pulse shaper (DSTAWG), and the asymmetric Fabry-Perot modulator (AFPM). This thesis covers development and modifications of the DSTAWG for incorporation into the word generator, and demonstrates reconfigurable direct space to time pulse shaping. The design of the AFPM is described and development of its fabrication process is discussed. The results of fabrication efforts to date are cataloged.
